The Research on Influencing Factors of Polymer Flooding
By using artificial non-homogeneous cores which coefficient of variation is 0.72 to simulate reservoir sandstone, and proceed the research of displacement effect on three aspects, which are polymer molecular weight, polymer solution concentration and reservoir permeability. The results show that polymer solution concentration and polymer molecular weight have greater influence on the displacement efficiency, while reservoir permeability has very little influence when it is more than 700md.
